Phys.org / Record snow drought drives water-hauling crisis for Rocky Mountain ranchers
As water shot into an open stock tank atop a high-country mesa, a trickle soaked the dusty earth below. Scott Snyder rose from the shade to fasten a hose and stop the spillage.
Phys.org / A lipid switch that blocks anthrax from entering cells
Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before ...
Phys.org / A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Phys.org / Why the future of fashion might involve wearing live fungi
The idea of having living fungi cover your body might not be the most appealing thing in the world. But what if it was part of a clothing fabric that could change color, protect you from UV rays and even repair its own tears? ...
Phys.org / How flying together helps Andean condors save energy
Animals are constantly moving to find food, water, suitable habitats, mates and safe places to rest. Because moving requires substantial energy, animals often rely on various biological and behavioral strategies to reduce ...
Phys.org / Astronomers identify one of the universe's rarest black hole events
A team of astronomers at the University of North Carolina at Chapel Hill has observed an extremely rare "wandering" black hole located tens of thousands of light-years from the center of its galaxy. This finding could reshape ...
Medical Xpress / Dreams drain energy: The REM sleep paradox
The brain demands a lot of energy compared with other organs. However, it can also make do when energy supplies are scarce, flexibly processing information using what is available. How the brain resourcefully allocates this ...
Science X / When darkness fell during the total solar eclipse, zoo animals responded in wildly different ways
Imagine a bright, sunny day suddenly turning dark as a solar eclipse sweeps across the sky. Even though humans have watched and recorded eclipses for thousands of years and now understand the science behind them, experiencing ...
Medical Xpress / Minutes-long process could create custom blood vessel grafts during surgery
Traumatic injuries, whether on a battlefield or in a car accident, often involve damaged blood vessels that require immediate repair. New research from Harvard bioengineers aims to make these critical, time-sensitive medical ...
Phys.org / Helical nanoparticles trigger cancer alarms and deliver gene therapy
Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while ...
Phys.org / More green space alone won't beat urban heat
New research from Victoria University (VU) reveals that reducing the impact of extreme heat in urban areas requires more than simply adding green spaces—it requires a different approach to urban planning.
Medical Xpress / Working memory rapidly updates its priorities after distractions, study finds
When humans tackle many everyday tasks, ranging from driving to completing household chores and work assignments, they rely heavily on working memory. This is the brain's ability to temporarily store and manipulate important ...
